摘要： In a vehicle steering system, in particular a steer-by-wire system, using a feedback control including an integral control unit in the feedback path, the integral factor of the integral control unit is made variable depending on the condition of the vehicle, road condition and preference of the vehicle operator so that the intensity of the steering reaction from the tires that is applied to the vehicle operator can be optimally adjusted. Thereby, the steering system can reduce the stead-state deviation and improve the stability in holding a steering angle both without any substantial compromise.

摘要： A current detecting apparatus comprises a determining unit which determines whether the electric potential of a first node or a second node is in a predetermined range. When the condition that the electric potential is not in the predetermined range continues longer than the predetermined period of time, the determining signal indicating the damage occurrence is outputted. Accordingly, the damage of the constituting elements can exactly be determined with the relatively simple configuration in a short time.

摘要： An electric power steering apparatus 1 comprises an electric motor 8, a vehicle speed detecting section (vehicle speed sensor) VS, a shifting state detecting section for detecting a shifting state of the vehicle, an engine rotational speed detecting section (engine rotational speed sensor) ES, and a motor control section (controller) 12 for controlling drive of the electric motor 8. The motor control section 12 includes a failure determination section (vehicle speed sensor failure determination section) 21 for determining failure of the vehicle speed detecting section on the basis of a vehicle speed, a shifting state and an engine rotational speed. The failure determination section 21 determines that the vehicle speed detecting section VS malfunctions if the engine rotational speed is equal to or greater than a predetermined rotational speed for a determinative continuous-time and/or a first determinative integrated time while the vehicle speed is zero and the shifting state is a vehicle driving state.

摘要： An electric power steering apparatus for a vehicle includes a protection circuit for stopping operation of an electric motor provided to apply a steering assist force to a steering system of the vehicle. The protection circuit is operable to stop operation of the electric motor when an ignition off signal is supplied from an ignition sensor and at least one of an engine speed signal supplied from an engine speed sensor and a vehicle velocity signal supplied from a vehicle velocity sensor falls below a corresponding predetermined value. Even if an ignition on signal is not supplied during movement of the vehicle due to a failure in the ignition sensor, when the engine speed signal or the vehicle velocity signal is above the predetermined value, the vehicle is regarded as being in the running state and operation of the electric motor is continued to apply the steering assist force to the steering system. With this arrangement, a good and stable steering feel can be obtained during movement of the vehicle.
